How transparent is the PET label paper?

The transparency of transparent PET label paper is very high, which is one of its important characteristics as a label material. Here is a detailed breakdown of its transparency:

Transparency overview

Transparent PET label paper has a high transparency, can clearly display the image and information. This high transparency allows transparent PET label paper to play an excellent role in a number of application scenarios, especially in the need to show product details or aesthetic effects.

Transparency indicators and detection

Clarity indicators: Transparency is usually closely related to the clarity of the material. Sharpness (also known as image sharpness, vividness, imageability, etc.) is an important parameter that characterizes the imaging ability or distortion degree of a material. For transparent PET label paper, the higher the clarity value of C%, the lower the distortion degree, the clearer the image. Transparent PET label paper has good clarity in optical properties, which can ensure that the printed image and information are accurately displayed.

Detection method: The transparency of transparent PET label paper can be tested by professional clarity detection equipment. Detection usually adopts the transmission method, that is, the use of light source through the sample after measuring the change of its luminous flux to calculate the clarity value of C%. This method can accurately evaluate the transparency properties of transparent PET label paper.

Influencing factor

The transparency of transparent PET label paper is affected by a variety of factors, including the purity of the raw material, the control of the production process, the use of additives, etc. High-quality raw materials and strict production process control can ensure that transparent PET label paper has a higher transparency. At the same time, avoiding the use of excessive additives or impurities in the production process can also reduce the negative impact on transparency.

In summary, the transparent PET label paper has a very high transparency and can clearly display images and information. This makes it useful in many applications.
